My girlfriend followed him and he messaged her then they exchanged phone numbers. I have already talked to my girlfriend about this and she tells me that there isn’t anything wrong with her making friends while with me. I feel controlling now and think I might just be over reacting now? Do you see any red flags or am I just being controlling? Here is the screenshot he sent me. He sent it to me because he wanted to know more questions about our relationship
